  [libc] Replace sys/select.h, sys/utsname.h and sys/wait.h includes with proxy headers (#209851)

I'm replacing system includes of <sys/select.h>, <sys/utsname.h>, and
<sys/wait.h> in non-test and non-proxy code with granular proxy headers.

- add proxy headers for sys/select.h and sys/wait.h macros as well as
fd_set, struct rusage, and struct utsname types
- switch select, uname, gethostname, and wait4 internal headers and
implementations to include the proxy headers instead of system headers
- update cmake dependencies for the affected entry points

Assisted by Gemini.

  [libc] Reimplement IN6_IS_ADDR_* macros using statement expressions (#209772)

This patch fixes three issues with the previous implementation:
- the macro argument was being evaluated more than once
- casting to other types (uint32_t in particular) was an aliasing
violation
- it was casting to non-const pointers, resulting in compiler errors in
cases where the user passes a const ptr.

A statement expression fixes the first issue by using a temporary
variable. The second issue is fixed by using the appropriate members of
struct in6_addr. The last issue is fixed by dropping the cast
completely. This requires the user to pass a correctly types pointer (as
POSIX requires). Implementations keep it for compatibility with old code
passing void * and similar, but a quick survey shows that most modern
code passes the correct types. If this turns out to be an issue, we can
easily add the cast (to a const type) back.

Implementation notes:
- IN6_IS_ADDR_MULTICAST doesn't use the statement expression because the
argument is evaluated only once
- I use private helper macros (__IN6_IS_ADDR_UNSPECIFIED and
__IN6_IS_ADDR_LOOPBACK) so IN6_IS_ADDR_V4COMPAT does not nest statement
expressions
- I considered using private entrypoints (like we do with cpuset macros)
instead of statement expressions, but decided against it because these
macros are simpler and would thus result in a higher
boilerplate-to-useful-code ratio (particularly given our restriction on
calling other entrypoints)

  [AMDGPU] Use v_pk_add_bf16 for scalar bf16 fadd on gfx1250/gfx13 (#209128)

Targets with packed bf16 instructions can do a scalar bf16 fadd with a
single `v_pk_add_bf16` operating on the low half, instead of promoting
to f32 and going through `v_fma_mix_f32_bf16 + v_cvt_pk_bf16_f32`.
